Pressing-in device for automobile control arm bushing

Abstract

The invention relates to a pressing-in device for an automobile control arm bushing. A left oil cylinder is mounted on a rack, one end of a left weighing sensor is fixed to a piston rod of the left oil cylinder, the other end of the left weighing sensor is connected with a left pressing head, symmetrically, a right oil cylinder is mounted on the rack, one end of a right weighing sensor is fixed to a piston rod of the right oil cylinder, and the other end of the right weighing sensor is connected with a right pressing head; a control arm fixing seat is fixed to the rack and plays a role in fixing a control arm, and meanwhile a void hole is formed in the position corresponding to the control arm bushing; a hydraulic station is mounted at the bottom of the rack, and the left oil cylinder, the right oil cylinder and the hydraulic station form a hydraulic system; and an electric control box is mounted on the upper portion of the rack, and output signals of the left weighing sensor and the right weighing sensor are connected with the electric control box. The pressing-in device can meet the pressing-in requirement of the automobile control arm bushing.

Description

technical field [0001] The invention relates to a press-in device, in particular to a press-in device for an automobile control arm bush. Background technique [0002] The suspension system is an important part of the car, which has a great influence on the ride comfort and handling stability of the car. As the guiding and force-transmitting element of the automobile suspension system, the automobile control arm transmits various forces acting on the wheels to the body, and at the same time ensures that the wheels move according to a certain trajectory. [0003] The control arm of the car elastically connects the wheel and the body of the car through a ball joint or a bush respectively. Automobile control arms, including the bushes and ball joints connected to them, should have sufficient rigidity, strength and service life. When working, the control arm bushing is connected to the subframe through bolts, which can buffer the impact of the road on the body and improve driv...

AI Technical Summary

Problems solved by technology

However, due to the irregular shape of the control arm of the car, there is no proper positioning reference, and the control arm is not easy to align, so it is very easy to have quality defects such as control arm slippage and bushing crookedness during press-fitting, and even pose safety hazards; moreover, The pressing efficiency is extremely low and cannot meet the requirements of mass production at all
